Mobo with PCI-e 16 and Card says PCI-e 2.0 Tags: Radeon Motherboards PCI Express Graphics Last response: January 8, 2011 5:16 AM in Graphics & Displays Share Lohengramm January 8, 2011 4:56:54 AM Hello folks, so heres the story. My mobo has a PCI-E 16x (running at 16x) and i'm planning on buying a HD5770 1GB GDDR5 XFX, The card says it needs a pci-e 2.0 port. So the question is, can I use the card on my motherboard? And if I do, how does it affect it? What are the differences between PCI-E 16x and PCI-E 2.0 16x? It will bottleneck, and how? My specs are: Phenom II x4 920 @ 2.8Ghz (Stock) HD4670 1gb ddr2 Mobo Gigabyte M68M-S2P 4Gb RAM (800Mhz) 1TB HD Western Digital PSU 550w. Thanks in advance and forgive me for my ignorance, googled already and found no answers.

There are some compatibility issues between a PCI-e 2.1 card and a PCI-e 1.0 slot. I have a HD 5850 (PCI-e 2.0) running just fine in my Abit mobo which has a PCI-e 1.0 slot. m 0 l Lohengramm January 8, 2011 5:16:56 AM HD5770 is needs a PCI-e 2.0, not 2.1. Mine is 1.0.
